FLUID'EJEOTOR.

SPECIFICATION forming part of Letters Patent No. 356,647, dated January 25, 1887/ Application filed December 17, 1836. Serial No. 221,863. (No model.)

To all whom it may concern:

Be it known that we, CLARENCE M. Knnr and CHARLES E. KEMP, citizens of theUnited Stat-es, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Fluid-Ejectors; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in fluid-ej ectors; and it consists of parts and combinations of parts, as hereinafter described, and pointed out in the claims, whereby the valve governing the ejector is operated quickly when the fluid rcachcsagiven height within a chamher in which the apparatus is located and closed quickly when the fluid falls, to give a sudden and effective pressure and cut-0d action to the ejector.

Our invention is illustrated in the accompanying drawings,in which Figure 1 isa front view of the device in connection with a well or tank, an ejector, and supply and discharge pipes; Fig. 2-, a side view of the valveoperat-ing mechanism; Fig. 3, usimilar .view of the opposite side of the same; and Figs. 4, 5,

6, and 7, details.

In the drawings our device is shown as applied to a well or cellar for draining water therefrom, and A is a tank or box in which the apparatus is placed; but the apparatus is applicable to any receptacle from which it is desired to remove water or other liquid.

The device is entirely automatic in character, as will be seen by the following description of its parts and operation. B is an ejector of any ordinary form placed in the receptacle, to which is attached a pressuresupply pipe, 0, con nccted with a waterservice pipe, D, and a discharge-pipe, E, to be carried out under the pavementto the gutter or sewer, or any other point at which itis desired to discharge the water or other liquid.

F is a valveseat located in a section, G, of the supply-pipe, and provided with three passages-onelower, d, and two side passages, cldi F is a balanced plogwalve, (shown in detail in Figs. 4 and 5,) having a cut-out portiomf, and provided also with a cap, f, having a nc t 9, under side of which projeotsapin, g. Ahead, 71, formed on the valve-scat,and through which the valve-plug extends and against which the valve-cap f bears, has a recess or cutoutpor tion, i, formed on one side thereof, in which the pin 9 moves and its motion limited, as hereinafter described.

Above the valve and on section Gis formed a. boss, L, and a lug, L. To the boss L is secured a short stud, In. On this stud is pivoted a weighted lever, N, which is shown in detail in 7. It is composed ofalong arm. 0, to the end of which a weight maybe secured in any suitable manner, and its opposite end terminates in forked arms I? P". It is provided on its front face with a projecting lug, R, and on its rear face with lugs r 2', which at the proper time bear against the log L on the section G.

thereon, and an ear, g, from the Thelever and all its parts,cxccpt the weight,

are formed in one piece.

S is a float-lever, also pivoted on stud in, and at which end it is provided with short projections s s, all in one piece with the lever, and at the outer end with o, float, T.

The operation of the device is as follows: Assuming that the supplypipe is closed, as the water accumulates in the tank or receptacle in which the apparatus is located, it causes the float'l and float-lever to rise until one of the pr0jeotions,s, reaches the 1 ug R on the weighted lever, and thus as the float-lever continues to rise the Weighted lever is brought to and finally carried beyond a perpendicular posi tion, and, falling toward the opposite side, one

of its forked arms, P, strikes the tuppet g on the face of the valve-plug and opens the valve, so that water is suddenly and quickly admitted down the supply pipe. The extent of the movement of the weighted lever is controlled at the same time by one of the lugs, r, on the lever coming in contact with the lug L on the section G. At the same time the extent of the movement of the plug is limited by the pin g extending from the back of the face-plate of the plug into the recess on the hub of the pipe, as above described, thereby allowing the valve to move only far enough to close and open completely. The valve when opened permits the water to flow through it from the side passages of the seat, and thence through the bottom passage out the pipe again. The cut-out portion f of the valve lessens the area of frictional surface in contact with the valve-seat; also, when the yalve is opened as the water rushes with greater volume to the ejector than the latter can at once discharge, the cut-out portion equalizes the back-pressure on the valve by permitting the liquid to flow. above it. Thus, by the reduction of the frictional surface of the valve, and the equal surfaces of contact being directly opposite each other, and the fluid under pressure entering through ports also so arranged, the balancing of the valve is maintained and, ease and quickness of operation obtained.

It will be seen that the valve is not encumbered by any lever mechanism pivoted lor keyed thereto, so that the same is free to act without the least resistance, and that in view of its balanced condition and the restrictions above described placed upon its movements and the movement of the weighted lever it is also ,freefrom all strain, jamming, and undue shock, which, when existing, soon render a valve stiff, uncertain, and inefficient in action. The ejector being thus put in action continues to eject the water from the receptacle through: the discharge-pipe until the water therein recedes and is discharged and the floatleverfalls, when areverse movement of the weighted lever is produced, the opposite proj ections, s, of the float-lever engaging with the single lug onthe weighted lever, causing the latter gradually to reach the perpendicular position, then to fall back, its opposite forkedi arm, P, engaging with the pin on the valve plug, turning the plug, closing the valve, cutting off the supply, and stopping the operation.

In our apparatus but two levers are em,- ployed, having integral therewith all parts engaging and controlling the independent valve, thus reducing and simplifying the number of parts, decreasing the expense of construction, and increasing the efficiency of the device.

What we claim is- 1. The combination, with pressure and discharge pipes, and an intermediate ejector com municating with the cellar or receptacle to be drained, of a valve in the pressure-pipe, a

weighted lever, and a float-lever, both pivoted to c the pressure-pipe independent of but adapted to connect with the valve, said float-lever arranged to operate the weighted lever, whereby the valve is operated quickly when the liquid reaches a given point, substantially as described.

2. The combination, with the pressurepipe,

of a a weighted lever and a float-lever, the lat 6o ter arranged to operate the former, and each separately pivoted on a suitable support, and a valve in said pipe disconnected. from said levers, but adapted to be operated by the weighted lever toiproduce a quick opening of the valve, substantially as described.

3. In a liquid-ejecting device, the supplypipe provided with the valve-operating mech: anism consisting of the weighted lever and float-lever, both disconnected lfromand sup- 7o ported independently of the valve, and each pivotally connected tosaid pipe, theweighted lever adapted and arranged to be operatediby the float-lever, substantially as descrilo'edl 4.
